The associative property has been used in step 3
Step-by-step explanation:
There are multiple properties that are used to solve the equations
One of them is associative property.
Associative property states that the order of three terms which are being added doesn't matter the result will be same.
In step 2:
As we can see that the last three terms are being added
The solver has used the associative property to solve the expression.
![2 + 2x + [10 + (-10)] + 11x](https://tex.z-dn.net/?f=2%20%2B%202x%20%2B%20%5B10%20%2B%20%28-10%29%5D%20%2B%2011x)
The brackets have been changed from

If you have a graphing calculator, you could use it to solve this question.
If you have a TI-84, go to <em>MATH</em> then <em>PROB</em> then <em>3: nPr</em>
From there, all you have to do is type in 7 and 3 in their correct spots to get 210 as your answer.
No because even though they are the same number they all have different meaning and amount but what is the same 4-5
7. 8+7=15 and 15/2=7.5 BUT they are asking for FULL LESSONS so it cannot be a decimal. Therefore it is 7.
Answer:
The sales tax rate is 8%.
C. The sale price is 20% less than the regular price
Step-by-step explanation:
Here are the options to this question :
A) The sales tax rate is 6%
B) The sales tax rate is 8%.
C. The sale price is 20% less than the regular price
Sales tax rate = (tax paid / discounted selling price) x 100
tax paid = amount customer paid - discounted selling price
$73.44 - $68 = $5.44
($5.44 / $68) x 100 = 8%
The sales tax is 8%
Sales price = (discount / initial price) x 100
discount = $85 - $68 = $17
($17 / 85) x 100 = 20%
